Archive of the former Yahoo!Groups mailing list: tube synth diy

I cant wait i have all the tubes for the ts22 i believe and i have
one of the four band pass filters completed. Id love to put up those
schematics but id have to get permission from eric im sure and he
never publicly relases his schematics i dont belive. I suppose if
you maybe email him a few times you might be able to get something
from him. I just wish all information was free. Heres some
imformation on it


TS-22 is unlike any other "filter" or "filter bank" offered on the
market. It consists of four simple vacuum-tube bandpass filters.
Their center frequencies are offset by 1 octave from the previous
filter. Each filter is independently sweepable with panel knobs; or
they
are all sweepable in unison, using either a panel knob or in
external source of control voltage, such as an envelope generator or
LFO. (A special optoisolator does the job.)

Because these filters do not behave like solid-state filters
or "virtual analog" devices, they sound very different from any
other filter ever offered on the market.

And the TS-22 includes a vacuum-tube pentode voltage-controlled
amplifier (VCA) at its output, optionally usable in conventional VCA
fashion in a modular synthesizer, to impose an envelope loudness
contour on the filter output (using an external envelope generator).
TS-22's CV inputs are 100% compatible with all existing envelope
generators and
other modular-synth circuits.

Thus, the TS-22 constitutes most of the signal processing path of a
classical monophonic analog synth. Only with no transistors in the
path.



OH and the ts 21 is wild i really cant wait to try that one. its a
beutty!!!!.
